Detailed Description

SoSTLFileKit is a class for using STL files with Coin.

Class for using STL files with Coin. You can use it to read and write STL files, and convert back and forth between Open Inventor scene graphs and SoSTLFileKits.

STL files are 3D models intended for 3D printers, and is a format supported by a wide variety of computer-aided design programs. STL models are, because of their intended purpose, always representations of solid objects. STL is short for Stereolithography, the process used for 3D printing.

Ordinary STL models do not contain color information. There are, however, two extensions to the binary file format for specifying color. Currently neither extension is supported. This is caused by lack of sample models using the extensions and will be added as soon as such models are found. We have the specs on the extensions, and it should be pretty straight-forwards to implement, but we want to get it right at once since we have write support (we don't want to inadvertently create a third color extension ;).

When writing STL files, certain STL model criterias are not enforced by SoSTLFileKit. These are:

Since the color extensions are not supported yet, color information is not collected either when converting Open Inventor scene graphs to SoSTLFileKits.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since:
Coin 3.0

Member Function Documentation

static void SoSTLFileKit::initClass ( void  ) [static]

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoForeignFileKit.

SbBool SoSTLFileKit::identify ( const char *  filename) [static]

Returns wether or not filename is identified as an STL file.

SbBool SoSTLFileKit::readFile ( const char *  filename) [virtual]

Reads in an STL file. Both ascii and binary files are supported. For binary files, the color extensions are not implemented yet.

Returns FALSE if filename could not be opened or parsed correctly.

See also:
canReadFile, canWriteScene, writeScene

Reimplemented from SoForeignFileKit.

SbBool SoSTLFileKit::readScene ( SoNode scene) [virtual]

Converts a scene graph into an SoSTLFileKit. Useful for creating STL files.

See also:
canReadScene, canWriteFile, writeFile

Reimplemented from SoForeignFileKit.

SbBool SoSTLFileKit::writeFile ( const char *  filename) [virtual]

Writes the STL model to an STL file.

See also:
binary, info, canWriteFile, canReadScene

Reimplemented from SoForeignFileKit.

SbBool SoSTLFileKit::writeScene ( SoNode *&  root,
const char *  format = NULL 
) [virtual]

Converts the STL model into a native scene graph.

See also:
canWriteScene

Reimplemented from SoForeignFileKit.

void SoSTLFileKit::reset ( void  ) [protected]

Resets the STL model so it contains nothing.

SbBool SoSTLFileKit::addFacet ( const SbVec3f v1,
const SbVec3f v2,
const SbVec3f v3,
const SbVec3f n 
) [protected]

Adds one triangle to the STL model.

See also:
reset, organizeModel
void SoSTLFileKit::organizeModel ( void  ) [protected]

Should be called after the STL model is completely set up in the SoSTLFileKit through import from a file or from a scene graph. The model will then be optimized for fast rendering.
